我正在使用react redux进行登录页面。在用户向应用程序提供正确的id和密码后，它应该将用户重定向到主页。上面的错误在我使用时显示。如果我改为使用无错误显示，但页面无法将用户重定向到主页。
index.js
import ReactDOM from 'react-dom';
import 'semantic-ui-css/semantic.min.css';
import {BrowserRouter, Route,Switch,Router }from 'react-router-dom'
import {ConnectedRouter,routerMiddleware, connectRouter } from 'connected-react-router'
import { init } from '@rematch/core'
import logger from 'redux-logger'
import * as models from './models'
import { Provider } from 'react-redux'
import * as serviceWorker from './serviceWorker';
import Dashboard from './component/Dashboard';
import MasterForm from './component/MasterForm';
import LoginForm from './component/LoginForm';
import MobilityForm from './component/MobilityForm';
import CaseRecord from './component/CaseRecord';
import MovementMap from './component/MovementMap';
const middleware = routerMiddleware(history)
const history = require("history").createBrowserHistory()
const store = init({
redux: {
middlewares: [
middleware,
logger
]
},
models
})
ReactDOM.render((
<Provider store={store}>
<ConnectedRouter history={history}>
<>
<Route exact path='/' component={Dashboard} />
<Route exact path='/dashboard' component={Dashboard}/>
<Route exact path='/form' component={MasterForm}/>
<Route path='/mob' component={MobilityForm}/>
<Route path='/record' component={CaseRecord}/>
<Route path='/login' component={LoginForm}/>
<Route path='/map' component={MovementMap}/>
</>
</ConnectedRouter>
</Provider>), document.getElementById('root'));
serviceWorker.register()
效果.js
import { dispatch } from '@rematch/core'
import { push } from 'react-router-redux'
const headers = {
'Accept': '*/*',
'Content-Type': 'application/json; charset=utf-8'
}
export const user = {
login(body, state) {
console.log(body)
fetch(`${config.url}/login`, {
method: 'POST',
headers,
body: JSON.stringify(body)
})
.then(res => res.json())
.then(data => {
let nextState = this.loginDone(data)
console.log(data)
dispatch(push('/'))
return nextState
})
}
}
减速器.js
export const user = {
loginDone: (state, data) => {
document.cookie = `token=${data.token}`
return {
...state,
auth_token: data.token
}
}
}
models.js
import * as reducers from './reducers'
import * as effects from './effects'
export const user = {
state: {},
reducers: reducers.user,
effects: effects.user
}
LoginForm.js
import React from 'react'
import { connect } from 'react-redux'
import { Button, Form, Grid, Header, Image, Message, Segment } from 'semantic-ui-react'
class LoginForm extends React.Component{
state = {
username: '',
password: ''
}
render() {
const { username, password } = this.state
return (
<div className='login-form'>
<style>{`
body > div,
body > div > div,
body > div > div > div.login-form {
height: 100%;
}
`}</style>
<Grid
textAlign='center'
style={{ height: '100%' }}
verticalAlign='middle'
>
<Grid.Column style={{ maxWidth: 450 }}>
<Header as='h2' color='teal' textAlign='center'>
Log-in to your account
</Header>
<Form size='large'
onSubmit={event => {
event.preventDefault()
this.props.login(username, password)
}}>
<Segment stacked>
<Form.Input
fluid
icon='user'
iconPosition='left'
placeholder='User ID'
onChange={event => this.setState({ username: event.target.value })}
/>
<Form.Input
fluid
icon='lock'
iconPosition='left'
placeholder='Password'
type='password'
onChange={event => this.setState({ password: event.target.value })}
/>
<Button color='teal' fluid size='large'>Login</Button>
</Segment>
</Form>
</Grid.Column>
</Grid>
</div>
)
}
}
const mapDispatch = dispatch => ({
login: (username, password) => dispatch.user.login({username, password})
})
export default connect(null,mapDispatch)(LoginForm)
我尝试了StackOverflow中的许多解决方案，还检查了软件包版本。

终于解决了这个问题。我制作了一个名为store.js的新js文件来声明商店在这个应用程序中使用的东西。我添加了一行代码来指示init((函数中的reducers，如下所示：
store.js
import createHistory from 'history/createBrowserHistory'
import {routerMiddleware, connectRouter } from 'connected-react-router'
import { init } from '@rematch/core'
import logger from 'redux-logger'
import * as models from './models'
export const history = createHistory()
const middleware = routerMiddleware(history)
export const store = init({
models,
redux: {
reducers:{
router: connectRouter(history)
},
middlewares: [middleware,logger]
}
})
export const { getState, dispatch } = store
我遵循了这个https://github.com/rematch/rematch/pull/446以定义调度函数。
